It's an uncommon occurrence in the small community of Violet: a memorial honoring a murder victim.

And just a few blocks over, another one.

"I heard approximately nine shots. Pop, pop, pop, pop," said Gizelle Hills of Violet. "And when I heard the gunshots, I came out my house. He was laying right here.”

Hill said 19-year-old Truy Jones was like a son. Jones was her son's best friend.

"It's real hard on him right now, because he died in his arms," said Hills.

Tuesday just after 8 p.m. Jones was shot to death in the 3100 block of Daniel Drive in Violet.

Then Friday night 30-year-old Joseph Cosse was killed in the 2800 block of Tara Drive, the community's second killing in three days.

"Very concerning to us, particular in the same area. Our detectives have been out here every day trying to run down some leads, trying to determine if these two killings were connected," said St. Bernard Parish Sheriff James Pohmann.

He said the arrest of Grid Reddick, charged with second-degree murder, came less than 24 hours after Jones' killing. He addressed the angst among citizens worried that more crime in Violet could be the way.

"As they should be, we are as well. We have a lot of police presence back here. We're concerned that if this is was indeed the second killing, (it) was (a) retaliation killing, you know. Where does it end?" asked Pohlmann.

The community struggles to recover from a double tragedy.

"A big old loss, cause he loved all the children. He did for all the children. He just wanted a better community for everybody," said Jermaine Miller, who knew Jones.

Before Tuesday, the last murder in Violet was in January 2009.

The St. Bernard Parish Sheriff's Office is asking for the community's help in bringing the suspect in 30-year-old Joseph Cosse's death to justice.

Anyone with any information is asked to call Crimestoppers at 504-822-1111.

Forty years ago, one of the greatest boxing matches in history took place in an unlikely setting: the capital of the Philippines. Muhammad Ali's epic win over great rival Joe Frazier in 1975 became known as the "Thrilla in Manila."

Hillary Clinton did not have a State Department email account while she served as America's top diplomat, a senior state department official said Monday, and instead used a personal email account during her four years on the job.
